Paint.NET (sometimes stylized as paint.net) is a freeware general-purpose raster graphics editor program for Microsoft Windows, developed with the .NET platform, and endorsed by Microsoft itself. It has evolved from a simple replacement for the Microsoft Paint program into a program for editing mainly graphics, with support for plugins.
Initially, Paint.NET was released under a modified version of the MIT License, with the exclusion of the installer, text, and graphics. However, citing issues with the open source code being plagiarized by others that had rebranded the software as their own and bundled user content without their permission, the availability of the source code was restricted. In November 2009, the software was made proprietary, restricting the sale or creation of derivative works of the software.
Starting with version 5.x, many old plugins are unable to load, such as BoltBait's plugin pack, and is unable to work with Windows 7.
